TODO: use wsconsctl(8) instead of sysctl(8) for brightness control.

Make 'physical' element of the struct agp_allocate an uint32_t. This
is similar to what other kernels do (at least Solaris and Linux).
This patch should make xserver work again within an i386 userland in a
64 bits paddr_t world.
Thanks to Iain Hibbert for reporting the break, and providing initial hints.

Clear the any endpoint stall in the interrupt handler. All other
drivers do this and I am pretty sure we need to as well, though I have
yet to see a stall in the handler.
Add support for the Zoom 3095 USB Fax Modem. There are some problems
with this modem:
1) The CS descriptors were placed after all other descriptors rather
than in the Control Interface. This is true in both configurations
and is the issue this patch deals with.
2) Modem audio is not done on the modem. There is a second
configuration with an extra interface (3 interfaces) which presumably
is for handling audio. This patch does not support that.
3) The interrupts are raised a bit slowly. This means that pppd(8)
needs to wait a bit before trying to read from the link (i.e., just
before the get_input() loop in src/dist/pppd/pppd/main.c line 547).
If you don't wait, then DCD will not be detected high before that
first read and get_input() will drop the line. This is not a problem
if you use the "local" option to pppd(8) and ignore DCD, but that is
less than desirable.
4) You apparently have to toggle "RSDL (DCD) option"[1] when you
initialize the modem or you will never see a second DCD high interrupt
when redialing after a disconnect. Without this the pppd(8) "persist"
mode will not work. Presumably, some extra initialization is missing
from the driver for this chipset.
[1] Send the AT commands: AT&C0 followed by AT&C1 - doing it in one
command doesn't work. The AT commands for this modem are at:

2. Acquire the device before checking whether or not the get_limits
routine exists.
XXX There's still a bug in here somewhere that prevents setting of
XXX limit values after using 'envstat -S'
